WIRE BAND FOR BOXES.

SPECIFICATION forming part of Letters Patent No. 304,308, datedSeptember 2, 1884.

Application filed June 17, 1884.

To all whom it may concern.-

Be it known that I, HIMAN FRANK, a citizen of the United States, and aresident of New York, county and State of New York, have inventedcertain new and useful Improvements in \Virc Bands for Boxes, 850., ofwhich the following is a specification.

This invention relates to wire bands for boxes, and is an improvement onthe invention covered by the United States Letters Patent to XV.Haeckel, No. 246,672, dated September 6, 1881, which is for a wire bandcomposed of twisted -wire strands, and having eyes or openings for thereception of the nails formed by outward bends of the strands, the twistbeing in one direction throughout the whole length of the band. It isessential in bands or fasteners for boxes which are provided with eyesor openings for the reception of nails that all the lines or openings bein one plane; otherwise difficulty is experienced in applying the bandsto boxes, &c. To insure this alignment of .the eyes in bands composed oftwisted strands of wire is the object of this invention, which end Iattain by twisting the wires in opposite directions in the alternatingsections of the bands between the eyes or openings, so any tendency ofan uneven twist due to one of the strands being harder than the other,or from other causes, which would throw the eyes out of line, in aprogressive manner, in one direction, if acontinuous twist in onedirection he made throughout the whole length of the band, iscounteracted by this reverse twisting of the alternate sections, for thedifference between the planes of two consecutive eyes will be veryslight, and as this change of plane is reversed in each alternate eyeall of them are practically in one plane. This double-twisted wire bandhas also an advantage in its application for any torsional or sidestrain which would tend to free it from the nails passed through theeyes, will twist it on one side of the nails as much as it untwists iton the other, so that the liability of this class of band becoming looseis lessened.

In the accompanying drawings, Figure 1 represents a portion of atwisted-wire band made (No model.)

according to my invention, and Fig. 2 illustrates the application ofsuch bands to a box.

To make the bands with a double twist, the strands a and b are twistedtogether in the first section in a right-hand direction;

they are then spread apart so as to form the eye or opening 0, and arebrought together again, and in the second section are twisted in aleft-hand direction, and are then spread apart in the same plane asbefore to form the eye 0, when a right-hand twist is again given thestrands in the next. succeeding section to the eye 0', and so onthroughout the whole length of the band, alternately twisting them inopposite directions and spreading them apart in the same plane to formthe eyes. Now, it will be observed, that should the eye 0 be out of linewith the eye 0 by reason of one of the strands a or I) being harder thanthe other one, or from any other cause, such variation in the planes ofc and 0 will be very slight, as the distance between them is small, anda similar variation will occur between 0 and 0, but 0 will be twistedout of line in the opposite direction to c, and will consequently be inthe same plane with c, and the next eye in plane with 0, and so onthroughout the whole length of the band. Thus any variations in thequality or properties of the two strands will not materially affeet thealignment of the eyes. A single wire is shown used in each of thestrands. It is evident that two or more may be used, if desired, withoutaffecting the principle of the invention.

The manner in which the bands are to be used is clearly shown in Fig. 2,(I representing a box; a b, the duplex twisted bands, and

nating sets of sections being in opposite directions, substantially asset forth.

2. A band composed of wire strands having a right-hand twist for a shortdistance, then an eye formed by outward bends of the strands, then aleft-hand twist for a short distance, then another eye formed by outwardbends of the strands, and so on, substantially as set forth.

3. In a band for binding boxes, the combination of the wires a and b,twisted together in a right-hand direction, bent outwardly to form theeye 0, and then twisted together in a HIMAN FRANK.
